JOHN BRADY, 0F FALL RIVER, MASSACHUSETTS.

MUTE-KNIFE ROLLER.

Specification of Letters Patent. Application filed May 11, 1912.

Patente-51 Dec. 39, 1913. Serial No. 696,630.

To all whom it may concern Be it known that I, JOHN BRADY, of Fall River, in the county of Bristol and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Mote-Knife Rollers, of which the following is a specification.

My invention relates to carding machines and comprises a series of mote knives which are mounted to move with relation to the licker-in and serve to detach the impurities from the cotton, collect them and deposit them in a special place.

Mote knives heretofore have been fixed in place with relation to the licker-in, but by using instead thereof or in addition thereto mote knives having a traverse slow in relation to the speed of the licker-in they can be made to carry off the impurities instead of allowing them to be scattered, and at the same time are fully as effective as the stationary knives now in use.

My invention will be understood by reference to the drawings in which Figure l is a vertical section showing a fragment of the cylinder, also the licker-in and adjacent parts. Fig. 2 is a longitudinal elevation of one form of my mote knife roller, and Fig 3 is a vertical section of the lioker-in and a modification of the mote knife roller slightly enlarged.

A is the cylinder, B the licker-in, and C the stationary mote knives, all of usual construction and mounted in the usual way with relation to the other parts Such other parts of the shown are customary in machines of this character and hence are not described, nor are the means for moving various of the parts shown as they are of a character well known. 7

Below the licker-in (see Figs. 1 and 2) is mounted my mote knife roller which as there shown comprises a drum having a series of knives (Z projecting from its periphery and fixed thereto, the outer edges of these knives corresponding in character with the edges of the regular stationary mote knives C. At each end of the drum D are flanges D integral therewith against which the ends of the knives d abut or to which they machine as are .cleans the cotton of the machine.

no doubt may be attached so as to form a series of pockets (Z in which the fly and impurities will be caught when disengaged from the cotton.

The drum D is mounted on a shaft D which is supported and rotated in any suitable way, its speed of rotation being preferably quite slow compared with the speed of the licker-in.

The advantages of this construction are that when set below the licker-in as shown, it may be brought very close thereto and hence will prevent hard lap ends or any hard substance getting onto and jamming the clothing between the cylinders, and that it very thoroughly. More over it is self-cleaning as the motes, etc., when freed from the sliver drop into the pockets (Z and when the pockets are inverted during the rotation of the roller the motes fall out into a suitable receptacle.

Being made of heavy cast iron the device is very durable and will not require removal under ordinary conditions.

I have shown in Fig. 3 a modification in which E is a conveyer belt upon which the knives e are mounted by rivets or otherwise and which runs over shafts E by which motion is given to it and between uprights E (one of which only is shown) which form stationary ends to the pockets 6 The blades e in this construction perform in all respects the same function as in the other form of my device as do the pockets 6.

Other modifications of my invention will occur to those skilled in the art, my invention relating to a series of moving or rotating mote knives which engage and detach the motes and which preferably form pockets in which the motes are collected and from which they fall in a predetermined spot. If thought best the drum or the conveyer may be more or less perforated rather than imperforate as shown in the drawings, the conveyor in this latter case perhaps comprising a series of links hinged together. The drawings show my preference in this respect.

What I claim as my invention is:

1. The mote knife roller above described comprising a body having knives projecting therefrom forming pockets, and means for radially disposed about said drum and ex closing the ends of said pocket-s whereby the tending between the flanges, as described. motes may be collected in said pockets and deposited in a predetermined place.
